I dont know i never really counted... it hurts when i sleep, i awake with pains in places that dont exist and the cause is not the bed or mattress.
So i just stopped sleeping, only getting tiny naps here and there. My doctor says i'm doing something called, DaVinci Sleep (i dont exactly remember the name), thats where you naps for small intervals of like 1hr - 20mins an estimated total of 4-6hrs a day. Basically i nap... a lot, so my body feels like its slept a full night, when I really have not.
Back on Topic:
I do remember me setting a record (among friends) of a little more than 8 days, more like 195hrs. I awoke to massive headaches and a little bit of diarrhea and paranoia... it was worth it and i can see myself doing that again!
